Veld fertilisation trends over a decade in the central Orange Free State

Abstract

A factorial veld fertilization experiment with three levels of phosphorus (0, 200 and 400 lb superphosphate per morgen per annum) and four levels of nitrogenous fertilizer (0, 200, 400 and 600 lb sulphate of ammonium per morgen per annum) has been conducted over a period of 11 years on a climax Themeda veld and pioneer Eragrostis-Aristida veld at the Agricultural Research Institute, Glen.
